To all whom it may concern:

Be it known that I, WALTER H. NICHOLLS, a citizen of the United States, residing in the city of Boston, county of Suffolk, and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Safety-Razors, of which the" fol lowing is a full, clear, and exact specificanon.

M 1 invention relates to safety razors, and particularly to that type of safety razor employing a. detachable. flexible blade, and has for its object to produce means whereby such blade maybe securely held in position and easily flexed, thereby imparting rigidity to the cutting edge and bringing the same into proper cutting position, and the said invention consists of a. flexible guard plate, a-concave backing plate, and a handle attached to the said devices. and means controlled by the handle for rigidly clamping the saidiguard plate and backing together so as seeinrely to hold the blade between them. :util also of sundry details hereinaiiter explained and fully illustrated in the accompanying drawings, wherein Figure 1 is a side view of my improved razor showing the same open. Fig. 2 is a similar view showing the same closed.

3 is a front elevation. Fig. 4 is a rear elevation. Fig; 51s an inner plan view of the guard-plate and backing open. Fig. 6 is a top view of the razor. Figs. 7 and 7 are plan and side views of the blade. Fig. 8 is a. detail, in section, of a socket.

Like reference numerals indicate corresponding parts in the different figures of the drawing.

The handle 1 of the razor has at its outer end a socket 20, within which is a threaded openingwhich receives the threaded rod 2,

and this threaded rod is rigidly attached to Specification of Letters Fatont.

A. backing plate 11 is hinc plate 6 at 12, and is howeo as to present a concave :taee whereby the same may be flexed imparted thereto. A performed formed integral with the backing within said lug and extending across the perforz ition tlzierein pin 14 which receives hook inner face ot the flexible gl'illltlrini'a a recess 15 above the bossfwhic cient depth to receive the perforated i 13 and permit the'outer edge of the ba 11 to come in contact with the razor when in position.

Perforations 16 are flexible guardqilate at each sido'o't the 8 for the purpose of reiitlering"ti,ie same more flexible, and a bead may, if d sired, likewise be formed in the said guar. for the same purpose.

The razor blade 18 is illustrated and side view in h i and w, and i in plan new, it is perforated at 9 purpose of permitting the passage .1: lug 13. This razor blade is made i r ened upon one edge, or. if desired. upon both its edges. it it is sharpened u on both edges, it should be of such width that i the hinge 12 when its forward edge is adjusted to cutting position. The beta the blade guard plate ii transrxe i downward pressure exerted by the i of the curred backing plate 11, has of flexing the blade and thereby ini oi" hr; the cutting edge into intimate and relation to the guard.

The assembling of my de." ingly simple and will be from the toregoing .I H

The razor blade 18 is inserted upon the flexible guard 6 to proper cutting position, the hook 5 passing through perforation 19 in said blade. The backing plate is then swung down to its seat and the handle 1 tipped forward, throwing the hook 5 backward and into engagement With locking pin 14 in the slotted lug 13. he handle 1 Will then be screwed up on the threaded rod 2, and the end of slotted plate 3 will pass Within the ferrule 20 on the handle, bringing the said ferrule flush with the hub 8, and a further rotation of the handle will cause locking pin 14 to pass Within hook 5, etfectually securing the parts together, and will cause the concave backing plate to press with force upon the razor blade and the flexible guard plate, thereby flexing the said blade and guard plate, imparting the necessary rigidity to the blade and furnishing a proper out departing from the spirit thereof, and

I do not mean to limit myself to the precise embodiment shown and described, but

lVhat I claim and desire to secure oy Let- .ters Patent is:

1. In a safety razor, a blade receiving plate capable of being bent transversely,, a

backing plate contracting therewith at the edges and means controlled by the handle for clamping the same together, substantially as described.

2. In a safety razor, a blade receiving plate capable of being bent transversely, a curved backing plate, a guard on one of said plates, and means controlled by the handle for clamping the same together and flexing the blade between said plates, substantially as described.

3. In a safety razor, a blade receiving plate, a backing plate hinged thereto, a lock- 1ng projection in said backing plate, and a latch controlled by the handle for clamping the said plates together, substantially as de scribed.

4. In a safety razor, a blade receiving plate capable of being bent transversely, a curved backing plate hinged thereto, guard teeth on one of said plates and locking means for clamping the blade between said plates and releasing same, substantially described.

5. In a safety razor, a flexible blade receiving plate, a curved backing plate hinged thereto, guard teeth on one of said plates, a locking projection on the backing plate, and

a latch controlled by the handle for clamping and securing the said plates together, substantially as described.

6. In a safety razor, a blade receiving plate, a backing plate, guard teeth on one of said plates, a locking projection in the back plate, a latch pivotally mounted in the blade receiving plate so as to move longitudinally, and a handle controlling said latch, substantially as described.

7. In a safety razor, a flexible blade receiving plate, a curved backing plate, guard teeth on one of said plates, a locking projection in be back plate, a latch pivotally mounted in the blade receivingplate so as to move longitudinally, a threaded projection thereon, and a handle engaging said threaded projection, substantially as described.

8. In a safety razor, a blade receiving plate capable of being bent transversely, a flexible blade, a curved backing plate, a guard on one of said plates, and means for clamping sanie together, substantially as described.

9. In a safety razor, a blade receiving plate capable of being bent transversely, a flexible blade, a curved backing plate, a guard on one of said plates and means for clamping said plates together and adjusting and retaining the blade, substantially as described.
